Senior Full-Stack Engineer
I build web applications for clients and my own projects, modernize existing products, and make Android apps.
EasyCaptions A web app that generates subtitles for videos and lets you edit and export them.
What Is Meat? An interactive 3D scroll story about where meat comes from, available in 46 locales.
Sincere Bhakti A community platform for Gaudiya Vaishnava devotees with posts, articles, albums and channels.A little of what I build: TextFormatter for the web and Sadhana List for Android.
I started by building websites, then moved into full-stack applications. I’ve worked with client teams on larger systems, including a frontend migration for Strava.cz and bug fixes and new features for Škoda Auto.
I also created CoderMania, an open-source platform for learning to code, and a beginner JavaScript course in Slovak.

We agree on the goal, scope, and technical approach.
I build in small steps and review the changes.
I check the key user flows, run automated tests, and prepare the release.
